Be it known IthatI', CHARLES VACHTEM u,V citienof-the Unitedl States, and a resident of Broolrlvmin the .county of Kings and State otNew- York, haveinvented certain new and usefullmproi-'ements in Portable Electr-fie` Lights, of which the following is o specification.

The invention pertains'more particularly to improvements in the class of electric lamps designed to liel held in the hand and sometimesused as flash lights and at other times for affording a. permanent light for n short period,L and one object of the. invention Poniente ELEc'rn-o LIGHT.

The sleeve 17 screwed upon the upperl endfof the casing 10 is integrally formed4 with an interior downwardly extending band 23 Whirl., seid sleeve isiscrewed upon the casing l0. concentricallyenters said Vcasing andJinclines downwardly and inwardlyfro'm at their Kipper ends being disposed within the'uppc'r edge thereof, that ortion of the 'metalcon'necting vthe sleeve '1 proper with the 'bund Q3'-'fini'1lly engaging the. upper edges of, the casing and arresting the Sleeve and bxindin their downward movement. The band z3 serves to add durability` to the u per end portion f th'e lam struc-x ture :in :sa conducto. whichie in e ectrical connection with the up er'end of the eonvductor 20, es shown in "ig. 2.@ .The connection of the upper end of the conductor Q0 with the hund 23 is formed by recessing out the inner upper ortion of the casing 10 in line with the saicPconductor 20, as vnt 24, and thenphencling inwardly imd downwardly the upper end of' the said conductor 20 from seid recess .jmd finally securing the seid end by solder'or otherwise against the exterior surface of the band 23, as shown in Fig.- 2. The hand 23 may, of course, instead of being integral with the sleevel', be separately formed :ind secured thereto hysoldering or the like.

The cup 16 is flanged inwardly and down-V wnrdly nt its upper open end, as nt 25, forming an annular seat for ametul shellZtl, und :snidl flange 25 :it its inner lower edgesis formed with a series of tongues 37 which nre inserted through holes formed in scid shell :ind then bent upwardly ngninst the inner n to secure theshell ngnins't` 'the` cop 1G nndzso connecting;r the shell und cnpthzxt the two pieces muv belnindled as one. The'shell 2G has nn upper threndednnnular portion 28' to receive the lenshf ilding ring Q9 and thence seid Ashell hns its walls converged downwardly nud inwardly defining approximntelvn cone-shape. The lower end of the shell 26 is open and :it the edges of thc open-t innr therein said shell tightly und is secured by solder or the like to' :i threaded neck 2X0 onthe lower end of the reflector It.

The disk or plnte 33 is placed in electricnl connection with the lower. end' of the baterv by means of a spring 37: of customnrv character.

The circuit lcloser or v switch mechanism...

commises n .band 38 closely ,encompassing.ximv

the ontelrnsino IO-imd extendingV orerfth'erecess 92 formed therein. r'I "he middle Dortions of thehnndflextend outwardlv inthe said bund is ndrmted to have n rotnrv movement imparted to it to the extent permitted hv the'lngth of the slot 42. smid handheing morcdlin on'e'direction to effect the closing lso of the circuit between the adiacent endsol" the conductors 20` 21 and in the onnositedi rect-ion to `effect the breaking of the circuit between said conductors. TNithin the chamber of the band is secured a leaf-spring 43 Whose free end is of V-outline and Within the recess 22 of thecasing 10. llVhen the band 38 is in the position in which it is shown in Fifi. 3, the spring 43 is not in engra gement with the adiaccnt ends of the con duc-tors 2G, Ql, but Awhen the band is Inanualljv turned until the pin 4l reaches the other end of the slot the free end of said spring 43 will nass in between the adjacent ends of the conductors :'20, 21 and serve to electrically connect said conductors and 'complete the circuit.

lt will be observed that in accordance with mv invention the circuit` closer casing is not riveted to or in electrical connection with either of the conductors 2G, 21, and therefore that there is no normal electrical connection either between said casing (in this instance the hand 38) and the'lower cap i8 or between said casing and the upper can 1G. The lower cap 18 is not at any time in circuit, and hence the flash light as a whole may be nlaced in tool box or with any metal articles Without danger of the circuit being accidentallv made bv the con tact of the lamb With-the blade of tool or the like. rdinarily it has been customary in the construction of Vlash lights of lthe character in question to rivet the circuitcloser casing to a conductor corresponding Tith 21 and have one end of the circuit closer spring; in electrical connection with its casing, and in this way the casing was always in electrical connection with, the lower exposed cap on the exterior shell, and it has been customary to connect the upper end of a conductor, corresponding 'with 20, to the can on the upper endof the outer shel.l with which the reflector for the lamp was in electrical connection, and under these conditions it is plain that a metal tool. such as a screwdriver,lving against the circuit closer casing" and lthe upper cap oragainst the lower can and the uppercap o a flash light, would make the circuitand result in the battery being unnecessarily' consumed. Mv invention remedies the condition just stated, as hereinbefore explained..

A portable electric li ght of the class de' scribed comprising an exterior casing containing a battery and haring; at its upper end an electric lamp in electrical connection with said battery, a reflector having a threaded neck receiving said lamp, a lens and means for holding and attaching said linnn, reflector and lens comprisingr a threaded sleeve on said casing a threaded cap engaging said sleeve having an open center and. flanged inwardly and formed with tongues along its opening, a shell of approximately lnvcrced conc-shape entering said cap and secured thereto by'said tongues and having an onen lower'end'to receive 'the threaded neck of the reflector and a threaded upper end,y and a threaded lens-holding ring engaging the threaded upper portion.'I
